Question: When performing plasma arc cutting on stainless steel, the operator observes excessive dross formation on the underside of the cut. What adjustment should be made to minimize this issue?
Answer options: ✅ Increase the cutting speed
- Decrease the cutting amperage
- Increase the standoff distance
- Decrease the gas pressure
Correct answer: Increase the cutting speed
Explanation: Excessive dross in plasma cutting is often caused by a cutting speed that is too slow, which allows too much heat input and molten metal to solidify on the bottom edge. Increasing the cutting speed allows the plasma stream to move quickly enough to eject molten material cleanly.
